26、RMISSION FROM UL Preface This is the common UL and ULC Standard for Field-Replaceable Light Emitting Diode (LED) Light Engines. It is the First edition of both CAN/ULC-S8753 and ANSI/UL 8753. This Joint Standard was prepared by Underwriters Laboratories Inc., ULC Standards, and the Technical Committ

27、ee on Field-Replaceable LED Light Engines. The standard was formally approved by the UL/ULC Technical Committee on Field-Replaceable LED Light Engines. The efforts and support of the Technical Committee are gratefully acknowledged. Only metric SI units of measurement are used in this Standard. If a

28、value for measurement is followed by a value in other units in parentheses, the second value may be approximate. The rst stated value is the requirement. In Canada, there are two official languages, English and French. All safety warnings must be in French and English. Attention is drawn to the poss

29、ibility that some Canadian authorities may require additional markings and/or installation instructions to be in both official languages. Annex A, Annex B, and Annex C, all identifed as normative, form a mandatory part of this Standard. Note: Although the intended primary application of this Standar

30、d is stated in its scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. Level of Harmonization This Standard is published as an identical standard between UL and ULC Standards. An identical standard is a

31、 standard that is the same in technical content except for conicts in Codes and Governmental Regulations. Presentation shall be word for word except for editorial changes. Interpretations The interpretation by the SDO of an identical or equivalent standard shall be based on the literal text to deter

32、mine compliance with the standard in accordance with the procedural rules of the SDO. If more than one interpretation of the literal text has been identied, a revision shall be proposed as soon as possible to each of the SDOs to more accurately reect the intent. UL Effective Date A UL effective date

33、 is established by Underwriters Laboratories Inc. and is not part of the ANSI approved standard.

34、licable to eld replaceable light-emitting diode (LED) light engines rated up to 347 volts (nominal) and provided with integral lamp bases of other than the screw, bayonet, or pin type congurations typically found on incandescent or uorescent light sources. 1.2 This standard does not cover: a) LED de

35、vices that are integral components and which form a non-replaceable part of a luminaire, such that they cannot be tested separately from the luminaire; b) LED lamps or light engines with screw, bayonet or pin-type bases, intended as replacements for incandescent or uorescent lamps; or c) LED light e

36、ngines having a means of supply connection other than the lamp bases allowed by 1.1, such as custom wiring harnesses. 1.3 This standard does not cover the holders, sockets, and the like to which these LED light engines are intended to be mounted. Such products are covered by UL 8754 / ULC-S8754. 2 R

37、eference Publications 2.1 See Annex A for a list of publications referenced in this standard. Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 2.2 Where any clauses from other

38、standards are referenced in this standard, this is to be interpreted as meaning that all requirements of the referenced clauses apply, except where it is clearly non-applicable to the product being evaluated, or superseded by requirements in this standard. 2.3 Throughout this standard, the CSA and U

39、LC standard references apply to products intended for use in Canada, while the UL standard references apply to products intended for use in the United States. Combined references are commonly separated by a slash (“ / ”). 2.4 For the purposes of this standard, referenced text in the CSA C22.2 No. 19

40、93 / UL 1993, using the word “ballast” is understood to apply to LED drivers, while text using the word “lamp” is understood to apply to LED light engines. 3 Denitions 3.1 The following terms and denitions apply in this standard. 3.2 CIRCUIT, CLASS 2 In Canada: A circuit for which the isolation and

41、electrical output characteristics comply with either CAN/CSA C22.2 No. 223 or both CAN/CSA C22.2 No. 66.1 and the Class 2 requirements in CAN/CSA C22.2 No. 66.3, and that is therefore eligible to be installed as such in accordance with Section 16 of CSA C22.1.

44、ER SOURCE (LPS) A circuit for which the isolation and electrical output characteristics comply with CAN/CSA-C22.2 No. 60950-1 / UL 60950-1 requirements for LPS circuits. 3.5 DEVICE A general term for a light engine. A more specic term is used if a requirement applies only to a certain type of device

45、. 3.6 ENCLOSURE A material or housing provided to enclose parts and components that can involve a risk of re or electric shock. 3.7 INSULATION, BASIC The insulation necessary to provide basic protection against the risk of electric shock. This insulation may be in the form of vulcanized ber, an inor

46、ganic or polymeric material, or an air gap. 3.8 INSULATION, DOUBLE An insulation system comprised of both basic insulation and supplementary insulation. 3.9 INSULATION, OPERATIONAL Insulation that is necessary for the correct operation of the equipment but that is not relied upon for protection agai

47、nst electric shock. 3.10 INSULATION, REINFORCED A single insulation system with such mechanical and electrical qualities that it, in itself, provides the same degree of protection against the risk of electric shock as does double insulation. Note: The term “single insulation system” does not necessi

48、tate that the insulation must be in one homogeneous piece. The insulation system may comprise two or more layers that cannot be tested as supplementary or basic insulation. 3.11 INSULATION, SUPPLEMENTARY An independent insulation provided in addition to the basic insulation to provide protection aga

49、inst the risk of electric shock in case of breakdown of the basic insulation. 3.12 LAMP BASE The part of the device that engages the lampholder and makes contact with the electrical circuits of the lampholder. 3.13 LED ARRAY (LED MODULE) An assembly of one or more LED packages or dies on a printed circuit board or substrate, possibly with optical elements and additional thermal, mechanical, and electrical interfaces that are intended to c
